How to Create and Fund Launch Wallets for a pump.fun Bundle

If you have ever funded eleven wallets by hand, copying addresses one by one out of a spreadsheet, you know the feeling of checking the last one and realizing you sent the dev wallet's SOL to buyer 7. This guide is about setting wallets up once, properly, so launch day is just a launch.

#Which wallets you need

A bundled launch has two roles.

• The dev wallet creates the coin and makes the first buy in the same transaction. It also pays for the coin's accounts, the Jito tip and the platform fee.
• Buyer wallets buy in the same bundle, right after the dev. DevBundler supports up to 10 per launch, and the free plan allows fewer than Premium.

You do not need 10. Two or three buyers, or none at all, can be enough. Decide the number when you plan the split, then create exactly that many plus one spare.

#Creating the wallets

In DevBundler's wallet manager you can generate wallets in bulk, up to hundreds at once, or import existing private keys. For a launch you usually want new ones.

1. 1

   Generate

   Create the dev wallet and the buyer wallets in one go.

2. 2

   Label

   Give each a name you will recognize in a dropdown, like "Dev, coin X" or "Buyer 1".

3. 3

   Group

   Put them in a group for this launch, so you can tick the whole group in the launch form and the transfer tools.

4. 4

   Check balances

   The manager shows live balances. New wallets start at zero.

Labels sound like housekeeping, but they are what stop you picking the wrong dev wallet under pressure. If you reuse wallets across launches, relabel them so you can tell which coin they belong to.

#How much SOL each wallet needs

Every wallet needs its buy plus a small margin. The numbers:

The 0.003 SOL covers the wallet's token account rent and transaction fees. The dev wallet needs the same 0.003 SOL plus about 0.03 SOL more, which pays for the coin's own accounts. On top of that, the dev wallet carries the Jito tip (we suggest starting at 0.005 SOL) and the platform fee shown at confirmation. If this is your account's first launch, there is also a one-time lookup table setup of about 0.005 SOL.

For DevBundler's default setup of 1 SOL dev and 0.5 SOL per buyer:

Round those up. A wallet funded to the exact amount turns red the moment you raise the tip or the priority fee, and a red wallet blocks the launch. How much SOL to launch on pump.fun has more worked budgets.

#Funding them in one step

Instead of sending to each address by hand, use distribute.

1. Source wallet

   one wallet holds the total launch budget

2. Distribute

   pick the group, set equal or custom amounts

3. Launch wallets

   each receives its buy plus margin

4. Launch table

   shows every wallet's balance and what it still needs

Distribute sends SOL from one wallet to many, with either the same amount for each or a custom amount per wallet. You can send it all now. Premium can also schedule a distribution to go out over time on an interval. For a launch, sending now and checking the launch table afterwards is the simple path.

#The custody trade-off

DevBundler is a hosted app. When you generate or import wallets, their private keys are stored on DevBundler's server, encrypted with AES-256-GCM using a key derived from your password (argon2id) plus a server secret. The server uses them to sign launches and trades, which is what makes one-click launches and multi-wallet trading fast.

That is a real trade-off and worth being clear about. You are trusting DevBundler's server with the keys of the wallets you use in it. Some practical consequences:

#After the launch: getting SOL back

When you are finished with a coin, consolidate. It sweeps the chosen wallets back into one, optionally keeping enough for rent or closing token accounts so the roughly 0.002 SOL rent in each comes back too. With eleven wallets, that rent adds up to something worth recovering.

Then move what you want to keep out of the app entirely. With funded, labeled wallets ready, the next step is the launch itself: how to launch a pump.fun coin with a bundle.
